Firmware image for board BM5866, version 1.4, for a 16 MB flash chip, marked as tested and working, archived as an 8.39 MB RAR. No device model or brand appears in the name, so confirm the board code printed on the PCB. Technicians flash such dumps onto the SPI BIOS chip with a hardware programmer to bring back a board that will not post. Back up the existing chip before writing, and make sure the extracted image is 16 MB so it fits the chip.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
